PHPUnit coverage inspection

A tool to allow code coverage rules be defined per file. Set a minimum coverage threshold for every file and configure custom minimum coverage for existing files if the current test coverage is not up to standards yet. Inspection failure will be output in checkstyle format, allowing it to be imported in ci/cd tools.

Use case

Standard coverage calculation is calculated over the whole codebase. If for example the threshold is 80% and one file drops below 80% you never notice this because the overall coverage went from 87.6% to 87.4%. This package makes sure that that doesn't happen anymore and coverage is calculated on a per-file basis.

Supported formats

• Input: clover coverage.xml
• Output: checkstyle or gitlab

Installation

Include the library as dependency in your own project via:

composer require "digitalrevolution/phpunit-file-coverage-inspection" --dev

Configuration

File: phpfci.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpfci xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="vendor/digitalrevolution/phpunit-file-coverage-inspection/resources/phpfci.xsd"
        min-coverage="100"
        allow-uncovered-methods="false"
>
    <custom-coverage>
        <!-- directory based coverage rule -->
        <directory path="src/Lib/" min="90"/>
        <!-- subdirectories will superceed a parent directory rule -->
        <directory path="src/Lib/Config/" min="100"/>
        <!-- file rule will always superceed a directory rule -->
        <file path="src/Lib/Config/File.php" min="80"/>
    </custom-coverage>
    
    <!-- when 'allow-uncovered-methods' is set to false, override this behaviour for specific files: -->
    <ignore-uncovered-methods>
        <file path="src/Command/ExampleCommand.php"/>
    </ignore-uncovered-methods>
</phpfci>

Option	Required	Default	Description
min-coverage	yes	-	The minimum global coverage
allow-uncovered-methods	no	false	All methods should have atleast some coverage

or generate a config file based on existing coverage results

php vendor/bin/phpfci baseline --baseDir /home/ci/workspace coverage.xml ./phpfci.xml

The base directory will be subtracted from the filepaths in coverage.xml

Usage

Checkstyle format:

php vendor/bin/phpfci inspect coverage.xml --reportCheckstyle=reports/checkstyle.xml

Gitlab format:

php vendor/bin/phpfci inspect coverage.xml --reportGitlab=reports/gitlab.errors.json

Gitlab format to file and text output to stdout:

php vendor/bin/phpfci inspect coverage.xml --reportGitlab=reports/gitlab.errors.json --reportText

Text format to stdout:

php vendor/bin/phpfci inspect coverage.xml

php vendor/bin/phpfci inspect coverage.xml --reportText

Command line arguments

Option	Values	Description
argument 1	inspect, baseline	the command to execute.
argument 2	coverage.xml	the phpunit clover coverage input file.
--reportGitlab=[<file>]	filepath or if absent stdout	the file (or stdout) to write the gitlab format to.
--reportCheckstyle=[<file>]	filepath or if absent stdout	the file (or stdout) to write the checkstyle format to.
--reportText=[<file>]	filepath or if absent stdout	the file (or stdout) to write the checkstyle format to.
--config=<path-to-file>	phpfci.xml	the path to the config file.
--baseDir=<path>	defaults to directory of the output file	The root directory of the project, will be used to make paths relative.
--exit-code-on-failure	-	Set exit code to 1 when there are failures.

Note: if no --reportGitlab, --reportCheckstyle or --reportText is set, it will default to --reportText=php://stdout

Migrating from 1 to 2

The third required argument and --report has been removed, and should be replaced by: --reportGitlab=<file>, --reportCheckstyle=<file> or --reportText=<file>
